feat: add wagon performance report and export functionality

- Implemented  for Excel download of wagon performance report sections, including column width adjustment and timestamped filenames.
- Created  to compute derived wagon performance figures based on movements and status logs, ensuring consistency with API data.
- Enhanced  with new fields for tracking last movement and statistics window days for improved reporting capabilities.
